As I said in the subject, it's no surprise. The value you get for your $300-350 is unmatched! What I do find interesting is that it says the 22mm kit has been in the top 100 for 34 days - well before the $300 price tag. The 18-55mm kit has only been in the top 100 for 17 days which aligns with the discounted price.

Its pretty well known that the average buyer goes for price. Canon needs to get a large number of M series owners, so they can market lenses to them. They may even be a loss leader, just to establish a big user base.

The danger from doing this is that buyers expect a low price, and won't buy if they think the price will drop.
